Remember when the RPG maestros at Bioware made third person shooters? Don’t feel bad, most people don’t. MDK2 follows the adventures of a janitor in a high-tech battle suit fending off an alien invasion with the help of a mad scientist and a six-legged, gun-toting robot dog. It's never officially revealed in the game what "MDK" stands for, but fans theorized it stood for "Murder Death Kill"—all of which will happen to you plenty of times over the course of the game.
